Error with Grails Executor plugin, bean "persistenceInterceptor" not found

I installed the "executor" plugin into my Grails app to do some simple asynchronous processing; I'm not using Hibernate or any fancy persistence. Based on the documentation for the plugin, which can be found here https://github.com/basejump/grails-executor, the setup is very simple, just add the following to

, but according to the plugin documentation I don't have to. Do I have to write a groovy class that implements the PersistenceContextInterceptor interface, and wire that up as the "persistenceInterceptor" bean? In the Setup section of the documentation, there is no mention of this..

The persistenceInterceptor is referenced by the executor plugin configuration, so once you add the plugin to a Grails project, your code must wire up an instance of PersistenceContextInterceptor in resources.groovy. I mocked a class to implement the interface just to get around this for now, and it worked fine.
